The one-way valve of the type RHC is waterproof without oil recovery when it is closed. This valve can be threaded onto and incorporate into blocks of command. The holes of the housing are easily confeccionables. The one-way valve of the type RHC is available with decompression. A decompression suppresses the blows of relaxation that can occur when the pressure is high and the volume of the consumer is high.
Properties and advantages:
  • Valve for screw
  • Pressures up to 700 bar
  • Flow rates up to 200 l/min
  • resistant
Areas of application:
  • Industrial hydraulic systems
  • Construction machines

Use:

  • Block water-tightness of the hydraulic cylinder without leakage of oil in combination with control valves, sliding vane with oil leak.
  • As download return, when there are few flow rates of return oil flow higher than the flow rate for the solenoid valve-sealed to the time of retracting a hydraulic cylinder of double effect due to the higher ratio of surfaces.

Versions:

  • Valves without prior discharge (model RHC..) The element of the valve is a ball. Rapid release of the entire cross-section of flow a To B to debloquear. The switching speed of the piston is cushioned. This prevents practically the opening of a sudden and the possible impacts of relaxation. If despite this you can't avoid the above, it is necessary to mount a point of constriction in the supply line of the oil control or use a valve with a prior discharge.
  • Valves with prior discharge (type RHC..V) The valve is a piston spherical grinding (seat spherical) with non-return valve ball is mounted, which is opened during the unlock even before the main piston and releases a cross-section of throttling for relaxation without knocking the volume of the consumer. Should be used primarily for working pressures high temperatures and high volumes of consumer. A strangulation additional supply line oil control increases the effectiveness of the previous download.
